On our way to Takamatsu, the largest city on the island of Shikoku, a quick check online (using my iPhone) and we had our lunch destination in 鶴丸 (pronounced 'tsurumaru'), a small restaurant in the centre of town near the station.
The owner was really friendly and recommended a few things to us, as I guess it was obvious we weren't local and didn't know our udon. First on the list was 'sashimi udon', served cold over rice with some onions and ginger. It's eaten sashimi-style, in that you eat it by first dipping it in soy sauce. This cost just 100 yen (65p), and I ordered seconds. The udon was really smooth and surprisingly soft. It almost melts in the mouth! I somehow remembered that in the film 'Udon' it was said that you shouldn't chew Sanuki udon, but instead let it just slide down. Not sure how true that is, and I didn't fancy trying it in case I choked, but I can see how it could be feasible as the noodles certainly don't require much chewing at all. Shown next below is my hot ぶっかけうどん (served in slightly-watered-down sauce with meat, ginger and onions) which was very tasty, and after that my brother's かけうどん (served with meat in a thinner broth). As we paid and left, the owner asked us if we'd had a good experience of udon, which was really nice. Definitely a good first experience.
